There are not many corrections, just "mouth" to collect money. Better, I'll eat half of you. I know a doctor 1200 to 2000. I don't recommend porcelain if the teeth are not ugly or hopeless. I made eight teeth, including the front teeth, because my nerves were pulled out, and it tasted tasteless. It will take half a year to correct it! Be patient and persist! It's good to go to the Second Hospital of Medical University, but the director usually doesn't do it. It's his student or a further education doctor. Go to the first hospital of the city to find Dr. Feng! Teeth are not a small problem.
